'1 Claims. (c 144-1) My invention consists of a multiple tool woodofFig. 1, but showing a. modified guide construcworking machine adapted toperform a'plurality tion; of operations by means of individual toolunits. Fig. 11 is a face view of the tilting supporting individuallydriven and individually adjustable, block for the guide stem.

as hereinafter described. The machine as 8. Referring to the drawings,the supporting 5 whole comprises a suitable supporting frameproframework 2 is generally rectangular, having side vided with a covertop or table, preferably adand end walls and a suitable mounting basefor justable to varying inclination, and capable of rigid placement. Theframe is preferably made.

Each such shaft extendsthrough the sev- 50 of Fig. 6, showing'the jig saw actuatingmechaeraltool units, to wit, a rotary planer l8, a band nism; saw pulleyla, a. sand papering wheel 20, and a Fig. 9 is a detail sectional viewshowing the circular saw 2|. Shaft I1 is also shown provided prime moverconnected with the main shaft; with an additional tool unit 22, as amilling tool Fig. 10 is a transverse section on the line.X-X or thelike, for grinding grooving or rebating. v 55 Tool 22 is removablyapplied to one end of shaft I1 and clamped thereon by any suitablemeans, as washers and nut 23.

Each of the several shafts ll, l'la, Nb, and l'lc is provided with aspline-engaging clutch 24 of any suitable construction, whichco-operates with a companion clutch 25 of a freely mounted driven pulleyor sheave 2B. The several pulleys 26 impart driven motion to clutch 25of each tool shaft from a driving belt 21 in driving engagement with aplural groove pulley or sheave 28, freely mounted on the common shaftll. As shown, the driving belts or cords at one side of the shaft H arestraightly connected, and those at the other side thereof are crossedfor imparting proper direc-. tion of motion to the particular tool. Itwill be understood however that either arrangement of belt may beadopted, depending on the work in view.

The driving pulleys or sheaves 28 are of plural construction and each isgeared with a driving belt 29 to a similar driving pulley 30 of mainshaft 3i. Shaft 3! receives its power, either directly or throughintervening gearing x, y, z, from a controlled motor M mounted at anysuitable lo cation on the frame, either outside or preferably inside, inthe manner generally indicated in Figs. 2 and 9.

Each of the several clutches 24 is thrown into or out of engagement withits companion clutch 25 by means of a hand lever 32 pivoted at 33 on abracket 34 of the particular frame 9, etc. Levers 32 extend outwardlytoward the opposite open end portions of the frame for easy access andmanipulation, as shown in Figs. 2 and '4. By such construction andarrangement it will be readily seen that upon rotation of main shaft 3|either of the individual shafts as H may be utilized for rotation of itsparticular tool, the remaining'shafts Ila, Nb, and H0 being inoperative.Also that either of said shafts may be similarly selected for use andthe others rendered inactive as desired.

Pulley l3, above mentioned as the tool element of frame 9a, is oneof aseries of pulleys or band saw elements, hereinafter described.

By such construction and arrangement it will be seen that the planer l8may be elevated to operative position as indicated in dotted lines, Fig.4, extending through the appropriate registering clearance opening a. oftop plate 4. Also, that when it and the remaining units are inoperative,the pulley I9 may be raised for loose or non-driving engagement with theband saw, and tightened .for operation thereof by lowering frame 9a andsecuring it in its depending slotted arm l5, as in Fig. 4. Likewise, thesandpapering wheel 23 may be similarly raised as in Fig. 3 and thereheld for operation and then lowered, as may also the circular saw 2|.

The band saw 35, as is usual, is of a continuous strip form of properlength and passes around driving pulley l9 of shaft Ila and likewisearound similar idle pulleys 35 and 31.

Idler band pulleys 36 and 31 are rotatably mounted on studs 33 extendinginwardly from the mounting base portion and terminal of a bracket frame38. The base portion 40 is of block formation having, a flat base 4|adapted to seat onthe inwardly extending upper'edge portion of theframe;v 2. Base 40 has downward preferably divided extension 42 insliding and clamping engagement with a supporting shaft 43 mounted bybrackets 44 along the upper outer portion of frame 2.

Extension 42 is provided with tightening screws 45 by which it may belocated in operative position as in Fig. '7 or loosened and thrownoutwardly and down to inoperative position, as indicated, with the jigsaw frame, in dotted lines in Fig. 6.

When erected as in Fig. 4, and the band saw 35 is tightened by loweringpulley I9 by its frame 3a, the band saw is maintained in driving andguiding engagement with its pulleys. pulley i9 is raised the saw becomesslack and may be removed from pulley l9 and thrown outwardly throughslot 46 of the cover plate and clearance 41. The cover may then beraised as in Fig. 5 for such purpose, allowing for removal of the bandsaw from pulleys 33 and 3?.

Similarly mounted for longitudinal and tipping movement on shaft 43, isthe jig saw frame 48, as in Fig. 6, resting by its flat base it on aninwardly extending shelf 50a of the main frame,

around which the plate 4 closely fits, as indicated Frame 48 extendslaterally by a lug or gudgeon 52 pivotally connected by tightening bolt53 to a sliding block 54 engaging the shaft 43. Block 54 functions inthe same manner generally as extension 42 of the band saw frame 39, andmay be tightened thereon by similar bolts or screws. By means of thebolt connection 53 the frame 48 may be swung slightly one way or theother and secured to maintain the jig saw in vertical alinement. Frame48 arches over across the machine and is provided at its terminal with ahousing 55 surrounding a reciprocating stem 56.

Said stem is mounted in extensions 51 of the frame, providing bearingstherefor, and for spring 58 engaging a flange 59 of the stem and tendingto exert constant reaction upwardly for reverse movement of the saw inits alternating stroke action.

At its lower end stem 56 is provided with a,

It will thus be seen thatwhen pulley 28 is driven, pulleys l3, l4 and 26will also be driven, and that either may be thrown out of operation orthat either singly may be connected, as for operation of the jig saw 5|or circular saw 2! by its particular clutch mechanism. For operating thejig saw, pulley I4 is provided with a clutch I1 freely rotatable onshaft 13,.and a clutch 18 in spline engagement with said shaft isprovided with a lever 19 pivoted at 80 in the same general manner aslever 32.

been connected by its terminals, as in Fig. 6, and

guide 88. The band saw adjusted for vertical movement, it will beactuated by shaft 13 and its crank disk 12 so long as clutch engagement11-18 is maintained. Outer side shaft 43 is provided with adjustablering abutments 8| and 82, each provided with a set screw or the like,for limiting sliding movement whereby I adjustably mounted within thehead and secured by a set screw 84. At the lower end of spindle 83 is aterminal bearing 85 having a securing set screw 86 for fixed adjustmentof a cross pin or shaft 81 provided with a bifurcated terminal 35 ispositively guided between the sides of guide member 88 or adjustto theposition shown,

By the adjustment of spindles 83 and 81, suchguide may be located closely adjacent to the work for maintainance ofpositive action. By such means both the band saw, and the correctadjustment of the jig saw maintain each of these elements in desirableworking relation with their actuating means and the raw material beingoperated upon.

In Fig. 1 I show a guide members!) having a vertical face capable ofadjustment toward and from the circular saw 2| when elevated through itsclearance slot (1. Guide 98, which is of conventional construction, isconnected by pivoting bolt 9i with terminal 92 of a transverse shaft orspindle 93 which has sliding engagement through a block 94 provided witha securing screw 95.,

Block 94 is slidably mounted on a shaft 96 at the other side of themachine similarly mounted in bearings 4t, and block 95 is provided withsecuringset screws 91 by which it may be fixed y held on shaft 86 at anydesired position. See movement and adjustment of shaft 83 the guide somay be located at any desired disce from the cutting zone of the saw itto determine the width of the severed piece.

By pivoting connection 9! the face of de it may also be angularlyadjusted, as at righ i. a les providing alcontact face for the work atany other desired location. 'thus in cross cutting the piece may bemoved towards the circular saw against the de member, while the guideand its supporting arm are shifted along the shaft 88. v

I show also inFig. 10 a similar construction and mounting in which thespindle be is provided at its inner terminal with a guide st, pivotallyconnected by securing a 1 e 9% so as to adjust it to any desired degreeof inclination. By such means it is capable of being set to any desiredangle to form a bearing for a blank A so as to sheet a bevel planededge, as by ping it over the planer it. Guide so is capable of aconsiderable degree of additional adjustment, both longltudinallyandlaterally of the machine, and may be utilized in connection with anyoneof the various tool units, as will be readily understood.

Under some conditions it is desirable to slightly elevate the hingedcover plate t, as in jig and band saw cutting. For such purpose Iprovide a pair of lifting arms lull extending from a cross shaft iti,suitably supported in opposite bearings and having a downwardlyextending actuating lever M2. The latter is connected by a compensatingslot joint or otherwise I03 with an adjustingnut I04 of threaded shaftI05.

Said shaft extends-outwardly through bearing Hill of the main frame andis provided with a turning crank I01. By such means it is possible toelevate the table 4 as indicated in dotted lines to a limited degree andto lower it to its normal fiat position, as desired.

The construction and operation of the machine will be readily understoodfrom the foregoing description. It comprises in its entirety a number oftool units in very compact arrangement and withina comparatively limitedcompass of construction.

Each individual cutting, shaping, or finishing tool is capable ofindividual operation by and through the mounting, adjusting and drivingmechanism illustrated and as above described. All of the several partsare readily available and easily inspected. Each particular unit may beeasily removed or replaced without involving any extensive taking apartof the machine, and the several adjustments adapt it to a wide andvariable application of work of the different kinds ordinarily providedfor in asinglemachine.

By reason of the clutch mechanism and the raising and lowering means,every particular unit not desired for use at any particular time may bedisconnected and lowered out of operative position. The machine istherefore rendered entirely safe to the operator and the avoidance ofany liklihood of accident following the use of ordinary care anddiscretion in its use. It is comparatively of economical use of power.

It will be understood that while as presented the invention involves theuse of a certain number of tool units, others maybe substituted whereverthey are capable of being embodied and are adapted to the individualdriving and adjusting means disclosed. Also that changes or variationsmay be made in the construction, arrangement of parts, details, etc. bythe skilled mechanic or others, but that all such changes are to beunderstood as intended and within the scope of the following claims.
